Workshops Workshops at Ubicomp 2019

Overview of Accepted Workshops

1st International Workshop on Earable Computing (EarComp 2019)

Organizers: Fahim Kawsar (Nokia Bell Labs), Alastair Beresford (University of Cambridge)

Sensory earables are increasingly becoming a mainstream compute platform with a promise to fundamentally transform personal-scale human sensing applications. Over the past few years, a number of research efforts in the ubiquitous computing domain have sought to achieve useful, engaging, and sometimes ambitious behavioural analytics with sensory earables including studies of the human face; of emotion and stress; continuous monitoring of cardiovascular function; oxygen consumption and blood flow; and tracking eating episodes as well as dietary and swallowing activities. At the same time, we have started seeing commercial efforts such as Bragi's The Dash, Bose SoundSport, Jabra Elite Sport, and Sony Xperia offering music experience augmented with sensory services including fitness tracking, real-time translations and conversational agents. Naturally, earables are becoming an intense interdisciplinary area of study with many and diverse applications including HCI, empathic communication, behavioural science, health and wellbeing, entertainment, education, and security. However, as of today, earable computing lacks an academic forum to bring together researchers, practitioners, and design experts from academia and industry to discuss, share, and shape this exciting new area of research. We are organising this very first workshop on Earable Computing with a hope that this workshop will serve as a catalyst for advancements in sensory earable technology as well as present a clear sense of direction for the research community to proceed in this space. As a launchpad, we aim to leverage the Open Earable Platform, eSense, from Nokia Bell Labs. These devices are being shared with 50+ academic institutions to accelerate the research in this space. In particular, we expect the very first workshop will include participants from these institutions reporting on their research with sensory earables to bootstrap this community.

SCAH 2019: Addressing Grand Challenges in Healthcare through Smart Clothing

Organizers: Daniel Tetteroo (TU Eindhoven), Lucy E Dunne (University of Minnesota), Bruna Goveia da Rocha (TU Eindhoven)

This one-day, hands-on and thought provoking workshop at ISWC 2019 aims to explore the opportunities and obstacles for Smart Clothing in healthcare, and to identify the grand challenges for researchers in this area. We are seeking for synergistic contributions from a wide array of participants, e.g., from healthcare practice, engineering and healthcare research, clothing design, human factors, and human-computer interaction. Specifically, we invite potential participants to submit a position paper outlining their perspective on the opportunities and challenges for smart clothing in healthcare. Furthermore, we strongly encourage participants to bring their own examples of smart clothing (targeted at addressing healthcare challenges) and/or devices they currently use in clinical practice. These demonstrators will serve as a starting point for focused discussions on particular aspects related to smart clothing and healthcare. As a result of this workshop, we aim to draft a “Grand Challenges: Smart Clothing and Healthcare” position document that can serve as a future research agenda.

AppLens 2019: The 2nd Workshop on Mining and Learning from Smartphone Apps for Users

Organizers: Sha Zhao (Zhejiang University), Yong Li (Tsinghua University), Sasu Tarkoma (University of Helsinki), Zhiwen Yu (Northwestern Polytechnical University), Anind Dey (University of Washington), Gang Pan (Zhejiang University)

Smartphone apps are becoming ubiquitous in our everyday life. Apps on smartphones sense users' behaviors and activities, providing a lens for understanding users, which is an important point in the community of ubiquitous computing. In UbiComp 2018, we successfully held the first International workshop AppLens 2018: mining and learning from smartphone apps for users. In UbiComp 2019, we would like to run the second International workshop of AppLens 2019. It seeks for participants interested in characterizing users from their use of smartphone apps, discovering cultural and social phenomenon by analyzing app usage, recognizing app usage behaviors, studying smartphone apps, user privacy issues, etc. In order to attract more participants, we will open an app dataset consisting of sub-datasets. This workshop will include paper sessions, invited talks, a panel session, and Best Paper Award, to provide a forum for the participants to communicate and discuss issues to promote the emerging research field. Moreover, we will select a few accepted papers to be extended and published in a prestigious journal special issue.

Beyond Individuals: Exploring Social Experience Around Wearables

Organizers: Ting Pradthana Jarusriboonchai, Felix A. Epp, Thomas Olsson, Oscar Tomico, Eric Paulos, Andrés Lucero, Jonna Häkkilä

Many wearables are inherently social by nature as they are visible to nearby others. Wearables carry meaning that tells about wearers. Several are also designed to enable interaction between collocated people and enhance group experience. As technology becomes wearable, it shares the design space and faces challenges similar to traditional clothes and accessories. Thus, it is important to consider social and cultural aspects the technology engenders as wearers go about in different activities and contexts in their life. In this workshop, we look into the dynamic and communicative nature of wearable technology designed for both individuals and groups. This one-day workshop offers a space for researchers, designers, and practitioners who have designed and interested to discuss and share their insights and challenges in designing wearable technology as a social, communicative item. Together, we will explore different kinds of social experience emerging around the technology and ways to design the technology that yields positive social experience.

Continual and Multimodal Learning for Internet of Things

Organizers: Tong Yu (Samsung Research America), Shijia Pan (Carnegie Mellon University), Susu Xu (Carnegie Mellon University), Yilin Shen (Samsung Research America), Botao Hao (Purdue Unversity)

Internet of Things (IoT) provides streaming, large-amount, and multimodal sensing data over time. The statistical properties of these data are often significantly different by sensing modalities and temporal traits, which are hardly captured by conventional learning methods. Continual and multimodal learning allows integration, adaptation and generalization of the knowledge learnt from previous experiential data collected with heterogeneity to new situations. Therefore, continual and multimodal learning is an important step to improve the estimation, utilization, and security of real-world data from IoT devices. We aim at bringing together researchers from different areas to establish a multidisciplinary community and share the latest research in continual learning and multimodal learning for various IoT applications.


Organizers: Xinlei Chen, Shijia Pan, Jorge Ortiz

Real-world ubiquitous computing systems face the challenge of requiring a significant amount of data to obtain accurate information through pure data-driven approaches. The performance of these data-driven systems greatly depends on the quantity and `quality' of data. In ideal conditions, pure data-driven methods perform well due to the abundance of data. However, in real-world systems, collecting data can be costly or impossible due to practical limitations. Physical knowledge, on the other hand, can be used to alleviate these issues of data limitation. This physical knowledge can include domain knowledge from experts, heuristics from experiences, as well as analytic models of the physical phenomena.

This workshop aims to explore the intersection between (and the combination of) data and physical knowledge. The workshop will bring together domain experts that explore the physical understanding of the data, practitioners that develop systems and the researchers in traditional data-driven domains. The workshop welcomes papers addressing these issues in different applications/domains as well as algorithmic and systematic approaches to apply physical knowledge. Therefore, we further seek to develop a community that systematically analyzes the data quality regarding inference and evaluates the improvements from the physical knowledge. Preliminary and on-going work are welcomed.

EyeWear 2019: Third Workshop on EyeWear Computing

Organizers: Benjamin Tag (Keio University), Jamie A Ward (Goldsmiths University of London), Yuji Uema (J!NS Inc.), Kai Kunze (Keio University)

Intelligent glasses, head-mounted displays, egocentric vision devices, and similar “smart eyewear” have recently emerged as interesting research platform for a range of research fields including, ubiquitous computing, computer vision, and social sciences. As most of the human senses are situated on the head, we believe that these types of devices have significant potential as a research and product platform for a wide range of wearable assistive systems in human computer interaction. While early prototypes were too bulky to be worn on a regular basis in daily life, new devices, such as Google Glass, Holo Lense and J!NS Meme, look more and more like normal glasses, are light-weight, and allow for long-term use enabling new interaction paradigms. The proposed workshop will bring together researchers from a wide range of computing disciplines, such as mobile and ubiquitous computing, eye tracking, optics, computer vision, human vision and perception, privacy and security, usability, as well as systems research.


Organizers: Kazuya Murao, Yu Enokibori, Hristijan Gjoreski, Paula Lago, Tsuyoshi Okita, Pekka Siirtola, Kei Hiroi, Philipp M. Scholl, Mathias Ciliberto

The recognition of complex and subtle human behaviors from wearable sensors will enable next-generation human-oriented computing in scenarios of high societal value (e.g., dementia care). This will require large-scale human activity corpuses and much improved methods to recognize activities and the context in which they occur. This workshop deals with the challenges of designing reproducible experimental setups, running large-scale dataset collection campaigns, designing activity and context recognition methods that are robust and adaptive, and evaluating systems in the real world. We wish to reflect on future methods, such as lifelong learning approaches that allow open-ended activity recognition. The objective of this workshop is to share the experiences among current researchers around the challenges of real-world activity recognition, the role of datasets and tools, and breakthrough approaches towards open-ended contextual intelligence. This year HASCA will also welcome papers from participants to two challenges: the Second Sussex-Huawei Locomotion and Transportation Recognition Competition ( and the Nurse Care Activity Recognition Challenge ( in special sessions.

LDC 2019: Workshop on Longitudinal Mobile, Wearable and Ubiquitous Data Collection from Human Subject Studies

Organizers: Vlad Manea, Allan Berrocal, Alexandre De Masi, Naja Holten Møller, Katarzyna Wac, Hannah Bayer, Sune Lehmann, Euan Ashley

Individuals increasingly use mobile, wearable, and ubiquitous devices capable of unobtrusive collection of vast amounts of scientifically-rich human subject personal data over long periods (months to years), and in the context of their daily life. However, numerous human and technological factors challenge longitudinal data collection, often limiting research studies to very short data collection periods (days to weeks), spawning recruitment biases and affecting participant retention over time. The Workshop on Longitudinal Data Collection (LDC) aims at bringing together researchers involved in longitudinal data collection studies to foster an insightful exchange of ideas, experiences, and discoveries to improve the studies’ reliability, validity, and perceived meaning for the participants. We welcome contributions and discussions focused on methods, tools, and frameworks for collection, analysis, and interpretation of human subjects’ mobile, wearable, and ubiquitous data obtained over long periods.

Mental Health and Well-being: Sensing and Intervention

Organizers: Akane Sano, Saeed Abdullah, Jakob E. Bardram, Sandra Servia, Elizabeth L. Murnane, Tanzeem Choudhury, Mirco Musolesi, Glovanna Nunes Vilaza, Varun Mishra

Mental health issues affect a significant portion of the world's population and can result in debilitating and life-threatening outcomes. To address this increasingly pressing healthcare challenge, there is a need to research novel approaches for early detection and prevention. Toward this, ubiquitous systems can play a central role in revealing and tracking clinically relevant behaviors, contexts, and symptoms. Further, such systems can passively detect relapse onset and enable the opportune delivery of effective intervention strategies.

However, despite their clear potential, the uptake of ubiquitous technologies into clinical mental healthcare is rare, and a number of challenges still face the overall efficacy of such technology-based solutions. The goal of this workshop is to bring together researchers interested in identifying, articulating, and addressing such issues and opportunities. Following the success of this workshop in last three years, we aim to continue facilitating the UbiComp community in developing a holistic approach for sensing and intervention in the context of mental health.


Organizers: Santi Phithakkitnukoon, Teerayut Horanont, Yoshihide Sekimoto, Sourav Bhattacharya

PURBA-2019 is the eighth in this series building upon the successful previous PURBA workshops. It aims to bring together researchers and practitioners to discuss and explore the research challenges and opportunities in applying the pervasive computing paradigm to urban spaces. We are seeking multi-disciplinary contributions that reveal interesting aspects about urban life and exploit the digital traces to create novel urban applications that benefit citizens, urban planners, and policy makers. Preliminary and on-going research work are welcomed.

The Accessible Wearable

Organizers: Clint Zeagler, Peter Presti, Paul Baker, Thad Starner

The development and adoption of wearable technologies continues to gain momentum in both industrial and consumer product arenas. With wearable and on-body solutions offering new solutions to advance the future of work (especially in the new rapidly evolving gig economy), it is imperative that the people designing and creating wearable technology interfaces and devices understand the impact of their decisions on device accessibility and more broadly, usability. Individuals with functional limitations or other impairments could be left behind through poorly considered design of the new wearable technologies. This workshop will bring together experts in assistive technology, usability, and wearable computing to discuss ways to help designers and technologists create more accessible, usable, devices.


Organizers: Alejandro Sanchez Guinea, Usman Naeem, Philipp M. Scholl, Elena Di Lascio, Pei-Yi (Patricia) Kuo, Veljko Pejović, Alexander Seeliger, Cristina Mihale-Wilson, Muhammad Awais Azam, Max Mühlhäuser, Christian Meurisch

Ubiquitous personal assistance (UPA) refers to the next era of digital personal assistants. UPA refines and complements the current concept of Intelligent Personal Assistants (e.g., Apple's Siri, Google Assistant, Amazon's Alexa), by considering advanced personalization, proactive/autonomous support, a single point of ubiquitous assistance, the combination of different coordinated assistants, and the unobtrusive integration of the user in the loop to adjust the underlying machine learning models. This workshop is focused on advancing towards digital assistants that provide a high level of personalization, through proactive and effective support of users’ activities, in an unobtrusive manner. In particular, we wish to put forward the discussion on how digital assistants can provide unobtrusive guidance and support for specific endeavors of people’s lives, such as those related to training/education, professional, and personal activities. Furthermore, this workshop seeks to find novel ways to exploit cognitive aspects, such as users’ intentions, motivations, and emotions, to build digital assistants that better fit each particular user.


Organizers: Anja Exler, Alexandra Voit, Dominik Weber, Martin Pielot, Nitesh Goyal, Sven Gehring, Tadashi Okoshi, Veljko Pejovic

In the advancing ubiquitous computing, users are increasingly confronted with a tremendous amount of information proactively provided via notifications from versatile applications and services, through multiple devices and screens in their environment. Thus, human’s attention has been getting a new significant bottleneck. Further, the latest computing trends with emerging new devices including versatile IoT devices, and contexts, such as smart cities, smart mobility including vehicles, are even accelerating this situation. In such situations, “attention management”, including attention representation, sensing, prediction, analysis and adaptive behavior in the computer systems, are needed in our computing systems. Following the successful UbiTtention 2016, 2017, and 2018 workshops, the UbiTtention 2019 workshop brings together researchers and practitioners from academia and industry to explore the management of human attention and smart and ambient notifications with versatile devices and situations to overcome information overload and overchoice. In this workshop, we want to focus on a larger understanding of the different roles notifications can play in a wide variety of computing environments including the office, the home, in cars, and other smart environments.

The Uncomfortable Workshop: Exploring Discomfort Design for Wellbeing and Sustainability

Organizers: m.c. schraefel, Adrian Friday, Scott Bateman, Josh Andres

If you are interested in either sustainability or health or both, this workshop is very much for you: come get uncomfortable with us. Here’s the connexion between these two domains: according to the latest science of human physiology, we are wired to thrive by engaging in cycles of various kinds of discomfort, including thermal discomfort, hunger, social discomfort, fatigue to name a few. Intriguingly, there are two highly ubicomp relevant associations from the science of discomfort: 1) working with this discomfort has keen effects on our physical, mental and cognitive wellbeing and performance 2) working with this discomfort has multiple positive side effects to enhance sustainability. For example: being a little cooler than the standard 22C office can both save energy and improve cognitive performance. Fasting for certain periods not only has significant benefits around wellbeing and longevity, it has knock on effects for energy/food production. These are just two examples. This workshop will explores how to leverage the science of discomfort to improve human wellbeing and to improve sustainability as a side-effect. Our guiding questions in this exploration will be: how can we design ubiquitous technology for a lifecycle of deliberate discomfort: that is, how do we design this tech to prepare, practice and perform discomfort, brilliantly and perhaps especially when under pressure? How are the tools and interactions different for any phase? For example: if the goal is to bike to work in the UK rainy cold winters, to spend 30 mins a little chillier than usual, how might a system help a person prepare for that morning’s outing? What on the calendar could be cleared by when? Is route planning needed? A reminder the night before to lay out the rainwear ahead of time? Do the lunch making when? Where is the friction to discomfort? To explore fasting overnight for 13 hours, how help practice more whole-foodism prior to a fast? Thus improving nutrient availability and reducing work and energy costs of more prepared foods? We will use Design Jams as a key activity to explore and build up this Uncomfortable Design Methodology. Please see the workshop website to explore uncomfortable ideas for your own practice prior to the workshop, to have fun getting uncomfortable together. 1-2 page uncomfortable design ideas are solicited for participation in the workshop. The best 15 as judged by organisers will be included in the ACM digital Library. See the Website for more details and come get uncomfortable with us for science! There will be prizes.

WellComp'19: 2nd International Workshop on Computing for Well-being

Organizers: Tadashi Okoshi, Jin Nakazawa, JeongGil Ko, Fahim Kawsar, Susanna Pirttikangas

We have been experiencing that much of the influence from ubicomp technologies are both contributing better quality of life (QoL) of our individual and organizational lives, and causing new types of stress and pain at the same time. The term "well-being" has recently has gained attention as a term that covers our general happiness and even more concrete good conditions in our lives, such as physical, psychological, and social wellness. Active research in various ubicomp research areas (systems, mobile/wearable sensing, persuasive apps, behavior change, HCI etc.) are needed towards drawing the big picture of “computing for well-being” from different viewpoints and layers of computing. We will share the latest research in such various areas related to users' physical, mental, and social well-being. Especially, this year's special attention will be paid for "Well-Being Metrics" and "Well-Being Intervention".
